Each one of the secondary converters has a corresponding transformer having a primary winding associated with a primary alternating current (AC) signal and a secondary winding associated with a secondary alternating current (AC) signal. A secondary controller provides secondary control signals to the secondary semiconductor switches of the secondary converters with one or more time-synchronized, target phase offsets with respect to an observed phase of the alternating current signal (e.g., primary alternating current signal or the secondary alternating current signal) to provide the target phase offset (or targeted phase offsets) commensurate with or sufficient to support a required electrical energy transfer from the primary controller to the corresponding secondary controller (or secondary controllers).

An object detection system compensates for variations in transmission characteristics within an object passageway caused by, for example, dust or dirt. An object detection device includes a plurality of electromagnetic radiation emitters and detectors arranged in rows on opposite sides of a passageway. First lenses focus radiation from the emitters into a semi-columnated beams of radiation that together create a plane of semi-columnated electromagnetic radiation that spans substantially across a width of the passageway. Second lenses focus the received electromagnetic radiation onto corresponding ones of the plurality of radiation detectors. A controller receives a radiation intensity signal from the detectors, determines that its value is outside of a predetermined range, and adjusts an amount of electrical power supplied to the plurality of radiation emitters so that the value of the radiation intensity signal changes to become within the predetermined range.

In one embodiment, a hydroseeder has an integrated bale grinder. The hydroseeder includes a tank, an agitator, a plurality of grinding flights, and a basket. The tank includes an opening and is configured to hold a material slurry. The agitator is positioned below the opening and is configured to agitate the material slurry. The plurality of grinding flights extends from the agitator and is configured to grind a material bale as it is introduced into the tank. The basket extends from the opening of the tank and is configured to direct the material bale toward the plurality of grinding flights.

A mobile work machine includes a wireless communication system configured to receive a wireless communication signal from a transmitter corresponding to a machine component on the mobile work machine, machine component identification logic configured to obtain a machine component identifier, that uniquely identifies the machine component, based on the wireless communication signal, operation detection logic configured to detect a machine operation associated with the machine component and to generate component performance data correlated to the machine component based on the machine operation, and control signal generator logic configured to generate a control signal that controls the mobile work machine based on the component performance data.

An autonomous agricultural carrier vehicle, for carrying an agricultural implement includes a chassis with steerable wheels or tracks attached to a frame, wherein the frame includes a mounting apparatus for connection to the agricultural implement. The vehicle further includes an environmental sensor system for determining obstacles or elements present in the vicinity of the carrier vehicle and a control device for controlling the carrier vehicle or the at least one implement, wherein the control device is connected to a position determination system that captures and issues a position to create an autonomous agricultural carrier vehicle with which the impact force is not reduced. No additional tractor vehicle is needed for the implement and no operator is necessary during field work, wherein it is provided that position-dependent working instructions for the carrier vehicle are preferably stored in the control device.

A semi-closed loop hydraulic circuit includes a prime move, a first hydraulic circuit operatively coupled to the prime mover, and a second hydraulic circuit operatively coupled to the prime mover. The second hydraulic circuit is fluidly coupled to the first hydraulic circuit.

A hydraulic spray nozzle, a hydroseeding system and a method of dispersing bulk material with a hydraulic spray nozzle. The hydraulic spray nozzle may further include one or more of an inlet, a diffuser cone, an expansion chamber, one or more interior surface vanes, a converging nozzle and an outlet that fluidly cooperate with one another in order to increase the dispersal distance of the bulk material as it exits the hydraulic spray nozzle. In one form, the hydraulic spray nozzle is incorporated into a hydroseeding system or other bulk material dispersing system in order to apply seeds, mulch, fertilizer or related bulk materials over large swaths of land.

A method for reducing material accumulation relative to ground-engaging tools of a tillage implement includes receiving measurement signals from at least one accumulation sensor mounted to the tillage implement during a tillage operation. The measurement signals include a three-dimensional (3D) representation of an environment containing material accumulation relative to a plurality ground-engaging tools. The method also includes estimating an amount of material accumulation relative to the plurality of ground-engaging tools based on the 3D representation. Further, the method includes comparing the amount of material accumulation to an accumulation threshold. The material accumulation threshold is indicative of a given degree of material accumulation relative to the plurality of ground-engaging tools. Thus, based on the comparison between the amount of material accumulation and the accumulation threshold, the method includes controlling an operation of at least one component of the tillage implement to execute a control action for reducing the amount of the material accumulation.

An apparatus and system for adjustably controlling the position and depth of row closer wheels in no-till planting applications, the apparatus comprising a frame, a piston movably secured at the top to the frame, upper and lower parallel arms disposed about the piston and movably secured at one end to the frame and at the other end to a hub stem, and a set of piston arms each movably secured at the top to one of the upper or lower parallel arms and at the other end to the bottom of the piston. A closing wheel assembly having a closing wheel frame and a set of closing wheels pivotally mounted to a lever on a single axle assembly allows the operator to change the angle at which the closing wheels intersect the ground surface during use. Accordingly, as the angle of the lever is manipulated, the angle of the closing wheel pivotally mounted to that lever changes in the vertical and/or horizontal dimensions.
